Anti-corrosion mud pump

Abstract

The invention discloses an anti-corrosion mud pump. The anti-corrosion mud pump comprises a pump body, a driving mechanism located behind the pump body and a control mechanism connected to the driving mechanism. The pump body comprises a cavity, a piston, a feed valve and a discharge valve, wherein the piston is arranged in the cavity, the feed valve is arranged at the upper part of the front end of the cavity, and the discharge valve is arranged at the lower part of the front end of the cavity. Sealing die blocks are arranged on the discharge valve and the feed valve. A plurality of annular grooves are formed in the inner wall of the cavity, and lubrication rings are arranged in the annular grooves. Layered sealing ring belts are arranged on the outer wall of piston rings so as to be capable of adapting to the cavity of a certain tolerance range, and air leaking or cylinder scoring can be avoided when the layered sealing ring belts move in the cavity; when the cylinder scoring phenomenon occurs, graphite can fill scratches through the joint effect of the graphite lubrication rings and the graphite in the layered sealing ring belts, and therefore the self-healing function can be realized.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery, and in particular relates to an anti-corrosion mud pump. Background technique [0002] As we all know, mud pumps are widely used, but because mud pumps are easily affected by the environment, especially in humid and corrosive environments for a long time, conventional anti-corrosion mud pumps, because they only use paint for anti-corrosion , its service life is relatively short, and most of them will be scrapped after 1-2 years. It is difficult to meet the requirements of long-term use, which increases the capital investment of consumers in a disguised form. A kind of anti-corrosion water pump is disclosed in CN103671081A, including the pump body and the The water inlet and water outlet on the pump body are characterized in that a handle is provided at the upper end of the pump body, the internal wires of the pump body extend from the upper end of the pump body to the outside, the l...

AI Technical Summary

Problems solved by technology

There is a handle on the upper end of the pump body, which is convenient for the operator to carry directly or lift the machine. The internal wires of the pump body extend from the upper end of the pump body to the outside, which can ensure that the wires are not easy to be crushed and broken, thereby ensuring the safety of the operator. The lower part of the pump body is set There is a support, which can make the pump body more convenient to operate when it is working. There is a plastic shell outside the pump body, and a waterproof film is wrapped outside the shell; although it can play a certain anti-corrosion effect, it is a conventional water pump and cannot Applied to plunger pumps; CN201129304Y discloses an anti-corrosion pump, including a check valve and a flow-passing component fixed below the check valve, characterized in that a layer of anti-corrosion is set on the surface of the flow-flow component contacting the water flow Corrosion-resistant and wear-resistant protective layer, the thickness of the protective layer is 0.03-0.3mm, which only adds a simple protective layer, which does not improve the pump body, nor can it enhance the use efficiency of the pump body. Replace it with a new pump body after a certain period of time, and there is no technical solution to this problem yet
